upon the vender plate 4 and upon the annular ring 9 which also carries the casing 8.

The vender plate 4 is provided on its periphery with substantially rectangular sockets 10 disposed at regular intervals around the vender plate and these substantially rectangular sockets are designed to be presented by step by step rotation to the point of intervention of the coin. In other words, one rectangular socket is presented to the coin receiving station for each vending operation. Furthermore, these sockets are wide enough to permit sufficient initial movement of the vender plate and vender lever plate, to be described, to permit deposit of a perforated slug or coin in the coin compartment. Thus, the vender plate rotates continuously with a step by step rotation, while the vender lever plate 2 is swung through a predetermined segment for each vending operation and is returned to initial position after each vending operation, being used in conjunction with proper coin to eifect successive vending operations of the vender plate 4.

The vender plate 4, intermediate the rectangular cut-away portions 10, is provided with ratchet formations which may be designated 11. These ratchet formations are designed to cooperate with a spring-held pawl 12 to prevent return rotation of the vender plate. This spring-held pawl 12 also cooperates with the rectangular cut-away portions 10 to successively position these rectangular cut-away portions in alignment with the coin-receiving slot of the vending machine which is disposed within a radially extending hood 13 on the casting 1. 3E-

The casting 1 is preferably provided with a well 14 which is of segmental form and which lies substantially beneath the segmental path of travel of a good coin in the normal actuation of the vending mechanism thereby. This well 14 is provided in its base with spaced apertures 15 and 16 which lead into a coin compartment 17 and which are guarded from beneath by guard flanges 18 and 19. The aperture 15 is designed to receive perforated slugs or coins and the aperture 16 is designed to receive good coins, the manner in which this is accomplished being described hereinafter.

Located within the well 14 is a locking lever 20 which is pivoted at 21 and which has a pin 22 extending downwardly from the lower side thereof through an arcuate slot 23 in the base of the well so that it may be connected to a tension spring 24 which is in turn connected to a pin 25 on the base of the casting. This tension spring normally tends to maintain the free end of the locking lever 20 outwardly against a stop 26 which thereon as at and having its outer end nora cooperation with the depressions 27 and 28 of the looking lever 20. The pawl 29 is further provided upon its lower side with a downwardly depending toe 34 which is adapted, under certain conditions, to contact with the outer edge of the locking lever 20, and which is also designed for cooperation with a shoulder 35 to prevent the projection of a finger 36 of this pawl across the slot which initially receives any coin or slug introduced into the coin-controlled mechanism.

The vender lever plate is further provided with a radial coin receiving slot 37 and with an upstanding shoulder 38 terminating flush with one wall of said slot. The finger 36 of the pawl 29 extends vertically upward from the top of this pawl through an opening 39 in the vender lever plate and is provided thereabove with a laterally extending portion 36A which would project across the radial slot 37 in the vender lever plate but for the fact that, in the normal position of this vender lever plate, it is held retracted by contact of the toe 34 with the shoulder 35, as illustrated in Figure 2.

Immediately beneath the coin slot which is disposed within the hood 13 of the casting 1, is a shoulder formation 40 which cooperates with the base of the radial slot 37 in the vender lever plate to limit downward movement of the coin while the vender lever plate is in its initial position. This shoulder 40 is comparatively short and immediately adjacent thereto, in the normal path of movement of the coin is the slot or opening 15 which is designed to receive the perforated slugs or coins. Just beyond this slot 15 is a shoulder 41 which is designed to cooperate with a good coin while it is moving toward the opening or slot 16 through which it is ultimately delivered.

In the operation of this structure, after the insertion of a good coin and the passing of this good coin into the slot 37 of the vender lever plate, as illustrated in Figure 2, the movement of the vender lever plate in the direction shown by the arrow in Figure 2, immediately results in release of the pawl 29 from the restraining action of the shoulder 35 which has been hitherto exerted upon the toe 34 of this pawl 29. Immediately, the laterally extending portion 36A of the finger 36 moves against the side of the good coin and clamps it against the opposing wall of the slot 37 and the upstanding shoulder 38 of the vender lever plate. This clamping action occurs before the vender lever plate has moved the coin beyond the shoulder 40 and it remains effective to prevent dropping of the coin through the slot 15 as it passes thereover.

If there were no coin in position in the radial slot 37, initial movement of the vender lever plate toward vending position would immediately release the toe 34 from restraint by the shoulder 35 and the heel 33 of the pawl 29 would look either in depression 27 or depression 28 of the locking lever 20. However, with a goodcoin in position in the radial slot 3'7 and exerting pressure against the lateral extension 36A of the finger 36, the pawl 29 will be held in such position that the heel 33 thereof will escape the looking lever 20, as shown in Figure 3, so that the vender lever plate may continue on its movement towards vending position. As this movement progresses, the good coin is not only held in the radial slot 37 by the pressure of the finger 36, 36A, but it is supported againstdroppingby the shoulder 41 on the wall of the casting well. Continued movement eventually results in contact of the toe 34 of the pawl 29 with the outer edge of the locking lever 20 which has, prior to this time, extended across and blocked the coin deposit opening 19. The vender lever plate then moves on until the radial slot 37 reaches a position above the coin delivery slot 16 in the casting 1.

Just before it reaches this position, as let showniineliigure d, theheel 3310f the-pawl :29 contacts lWitlh a .cam surface .42 formed in th endwallofthenwell 14. ilhisswinsszthe paw 9 to such a position that the coin is relieved from the .pressureof the anemia-36A. .sh rt yaft wards, the radial slot vwith ,the ,coin :therein reaches a position above the coin delivery slot 16, andthe coin drops therethrough into; the coin compartment beneath the casting 1. Thevender:lever;plate is then returnedto initial position and the various parts described assume their .initial positions.

- In the operationof this structure, after .theinsertion of -.a perforated slug or coin, the parts being in the position illustrated in Figure;5,.:ini tial movementof the vender lever plate :-brings theperforatedslug or coin into the position shown in:Figure 6, wherein the lateralextension 36A of the 'finger:36 projects vthrcvughgthe aper-.

ture inithe slug or coin. Thismovement also releases the-toe; 34, ofsthe pawla29 from the restraining contact of the shoulder: andpermits this pawl 29 to swing outwardly to such ,an extent thattheheel'33thereof will catch in either the depression :27 or the depression 28 of the locking-lever 20. thatthe pivot of the pawl :29 swings in an are outside of the pivot of the lockinglever20, the vender levereplate may continue its movement so as .to-exert a-pressure uponthehook of the locking lever 20 of such a natureas to, slightly swing :this locking'lever inwardly and to also swing. the pawl inwardly to an extent sufficient to withdraw; the fingerfrom-the; hole in the-slug.

When this occurs, .the radial coin-slot with the slug therein isabove the coinor slug delivery slot 1 -5 .and the perforated slug or coin will drop through this coin delivery slot 15 and=into the coin'compartment beneath the casting 1. ;How

7 ever, this swinging'of the lockinglever 20 and thepawl329 is quitelimited and-they;remai n-in locking relation so that the vendenlevenplate is restrained from further movement toward delivery of the articles. As a; matter. of fact, the

i interlocking action of the pawl-with the locking leverto restrain further-movement of the-vendor lever plate issupplemented by the contactof the locking lever with the end wall .of-the well 14. As previously pointed out, the rectangular sockets 10 are wide enough-to permit the-occurrence of movement of the vender lever platesuillciently to ,depositthe perforated slug without contact with the slug or coin.

It will of course be obvious that thelocking-of the locking lever 20' and the pawl 29 as -well as their combined locking contact against the end wall of the well 14in the casting 1 occurs ina similar mannerwhen it is attempted to move the vender lever plate to vending position when no coin or slug-of any typeihas been deposited inthe radial slot 37 of the vendor lever plate.

=While-I have shown'and described my apparatus only in operation, either with agood coin or with a-perforated slugor coin, it will be understood that, upon theintroduction;ofaslug-or coin which is less than a given thickness. theope-rationwill be substantially the sameas that shown in:-F.igures.;5,t6 and .7.-:In otherwords, -a coin which is too thin will act, just as the perforated slugor coinwill, in that it will failto exertsuilicientpressure upon the-fingerg36, 36a to holdthe locking :pawl .29 out of:; the path of the depressions:2'7 and 28 ofathellocking lever 20.

herentfunction of myinvention and is intended I t rbe cove ed by these l mlt i1l beapparent that I have disclosed a novel form,;of coin-controlled mechanism whereinthe mechan smtvh .ui l z d the -an operation of the-vending machine upon the introduction of a good coin into the mechanism is aisopper-ative upon the introduction of a slug or coin of. objectionable character to automatically divert and sequester this objectionable slug or coin,,.while at thesame time leaving the vending m chanism a d h c in-c n ol m cha is in; such position that the vending operation cannot be performed. [Ifhe apparatus is of such. a naturethat it will automatically detect whether or not the slug or coin has an aperture therein oris too thin and, if so, will deposit this coin in -a locked; compartment without operating thevendingmechanism. If the slug orcoin is not objectionable, the vending mechanism will operate. Furthermore, this dual-function is obtained by-a single mechanism which is of extreme simplicity and of ru ed form. r
